CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a non-provisional application claiming the benefitof U.S. patent application Ser. No. 14/170,739 filed Feb. 3, 2014, whichis pending. The disclosure of U.S. patent application Ser. No.14/170,739 is hereby incorporated by reference for all purposes herein.

FIELD OF THE INVENTION

This invention relates to an apparatus that allows a user to move or bedisplaced in from one location to another along a zip line rail systemusing a rail.

This invention also relates to an apparatus and system to allow a personto safely maneuver and traverse a challenge course, zip track, zip line,and an integrated dual rail zip line. Participants are challenged towalk or scale various elements or obstacles while elevated above theground, which can test the participant's skills such as confidence orgroup problem solving.

BACKGROUND OF THE INVENTION

Challenge courses are structures that allow a person or team tochallenge themselves by participating in various events such as walkingalong swinging ropes or planks, at elevated heights. These courses arealso used to train military personnel. These courses are also used atrecreational parks or other such centers that have go-carts andminiature golf.

Zip lines are generally ropes or cables that are connected at both endsto fixed members of varying heights. In other words, one end is higherthan the other. A participant then, by use of a pulley that rotatablyengages with the rope or cable, glides from the higher end to the lowerend.

The present invention uses a fixed rigid member that is engaged with twowheels to allow the user to roll along the fixed rigid member in anynumber of directions and trajectories.

The invention uses a non-single point of failure member or cable slideor similarly functioning member that can be used in challenge courses,zip lines, and dual rail tracks to increase the safety by having a meansto keep the safety cable attached to the glide, as opposed to a singleweight bearing bolt.

Multiple embodiments of the system are disclosed herein. It will beunderstood that other objects and purposes of the invention, andvariations thereof, will be apparent upon reading the followingspecification and inspecting the accompanying drawings.

The challenge courses in the prior art usually have a single point offailure means extending downwardly from a moveable member within atrack, whereby if this means, such as a bolt, fails, there is nothingsecuring the user relative to the track, or securing the user frompossibly falling. Also, the member slide of the prior art do not havemeans for traversing on a dual rail track or system.

There exists a need for non-single point of failure member slide toincrease safety for the users. There also exists the need to increasethe safety while not decreasing the capacity of participants traversingback and forth from the challenge course, zip line, zip track, and adual rail track.

The present invention is a zip line rail system that allows a user tomove or displace from one location to another without effort on theuser's part. This movement or displacement may be performed primarily bythe force of gravity. However the present invention may also use alaunch system to provide the impetus for the member slide to move. Thisdiffers from the prior art in that it may be integrally connected to achallenge course, and a zip line that uses cables or ropes, or it may bea stand-alone system.

The present invention also, rather than using cables or ropes, uses afixed member, such as a rail, or beam or track along which the user isdisplaced via a glide or wheeled structure that glides or rolls on arail, or within the beam or on a track.

There exists a need for a zip line rail system that enables a user totraverse from a challenge course or a zip track to the zip line railsystem of the present invention in any particular order.

This allows the user to travel at higher speeds then a zip line using arope or cable due to the sagging that must occur in the rope or cablezip line. The present invention also allows for safer and more expedientmovement throughout the course because the user can stay engaged in thesame glide structure or wheeled structure throughout the system. Thissystem also allows the user to enter banked turns by offsetting theheight of two adjacent rails.

There also exists the need to increase the safety while not decreasingthe capacity of participants traversing the challenge course.

The present invention also uses a brake system to slow down the userusing the member slide.

Multiple embodiments of the system are disclosed herein. It will beunderstood that other objects and purposes of the invention, andvariations thereof, will be apparent upon reading the followingspecification and inspecting the accompanying drawings.

FIG. 1 illustrates an embodiment of the present invention 10, referredto as a zip line rail system 10 or zip line dual rail system 10. In oneembodiment a support member 20 supports plates 30 securely disposedintermittently thereon. The plates 30 may extend downwardly from thesupport member 20 to a rail 40. In one embodiment the zip line railsystem 10 may have two rails 40 with a distance 120 between each of thetwo rails 40 so that a member slide (FIG. 3) can be supported by thewheels 90 rollably disposed on the rail 40, and can extend downwardlybetween each rail 40 and not contact either rail 40. Or the contactbetween a frame 150 or member slide frame 150 can be incidental and notaffect the speed or direction of the member slide 80 as it is moved ordisplaced along the zip line rail system 10. In one embodiment the frame150 may be made of aluminum.

In one embodiment the plate 30 may have an upper support portion 50 toassist in dispersing force and assist in bearing some of the load of therails 40 and the person using the member slide 80. The plate 30 may havetwo plate arms 130 that extend downwardly and secure the rail 40 to eachrespective plate arm 130, as best seen in FIG. 2.

An arm 60 may extend from a wall, or other fixed structure 610, such asa challenge course 100, a wall of a building, or a column extending fromthe ground, to the support member 20 or an arm plate 70 that is securedto the support member 20. In one embodiment the plate 70 is thicker thenthe plate 30 to support more force and weight at certain locations, andmay assist in securing the arm 70 to either the support member 20 or thearm plate 70, or both the arm plate 70 and the support member 20. FIG. 1also illustrates how the zip line rail system 10 may be configured in avariety of directions, heights, or coordinates 140. As seen in FIG. 4,the zip line rail system 10 may be configured in a loop.

FIG. 2 illustrates another embodiment of the present invention 10. Thesupport member 20 is illustrated in a sectional view. In one embodimentthe support member 20 may be circular, although it may be any shape,including but not limited to square, hexagonal, triangular, or anygeometric shape. One function of the support member 20 may be to providethe majority of structural support for the zip line rail system 10.

The plate 30 may be secured to both the support member 20 and a rail 40downwardly there from. The plate 30may have two plate arms 130descending downwardly from the support member 20 to a respective rail40. In one embodiment there may be two rails 40 and they may beseparated by a distance 120. An arm 30 may be securely connected to asupport member 20, or to an arm plate 70, or to both the support member20 and the arm plate 70.

FIG. 3 illustrates an embodiment of a member slide 80 that may be usedwith the present invention 10. The member slide 80 may have a wheel 90to roll upon a respective rail 40. The member slide 80 may have a frame150 that may fit within the distance 120 and between each rail 40, andthe wheels 90 may roll upon each respective rail 40 so that the memberslide 80 can move along the zip line rail system 10. FIG. 3 illustratescomponents of the modified non-single point of failure member slide 15,which are shown in further detail in FIGS. 6 and 11. Said componentsdetailed in the drawing are the belt or strap 300 which may connect themember slide 80 to a harness worn by a person utilizing the presentinvention 10. FIG. 3 also illustrates the member slide 80 may have apuck 160 that may slide inside the challenge course 100. A lower disk165 and sheath 260 help protect critical load bearing components fromwear caused by friction while traversing through the challenge coursetrack 105.

In one embodiment, the sheath 260 may be Ultra-high-molecular-weightpolyethylene (UHMWPE, UHMW). The first member retention means 200 andsecond member retention means 210 bear the load when member slide 80 maybe contained by the challenge course track 105. The upper disk 170provides support to the puck 160. The puck 160 may be replaceable, as itmay wear against the inside surface of the challenge course track 105.The correlation between the member slide 80 and the challenge coursetrack can be seen in further detail in FIGS. 12 and 15. The rail 40 maybe adjacent to the challenge course 100 so the user may move from thechallenge course track 105 to the zip track rail system 10 without beingdisengaged from a safety harness. The member slide 80 may traverse froma rail 40 to a challenge course track by means of a PUCK KEY TRANSITIONSYSTEM, as disclosed in U.S. patent application Ser. No. 13/234,138, orthe ZIP LINE TROLLEY TRANSPORT SYSTEM, as disclosed in U.S. patent Ser.No. 12/750,970.

FIG. 4 illustrates an embodiment of the zip line rail system 10connected to a challenge course 100 so that a user may traverse from thechallenge course 100 to the zip line rail system 10. While in thechallenge course 100 the puck may be retained in the challenge coursetrack 105 as seen in U.S. Pat. Nos. 7,174,534, 7,416,054, 7,981,004, or8,066,578.

FIG. 4 illustrates the zip line rail system 10 may have a variety ofdirections and configurations. For example, it may go up, down, left,right, or any combination of any type of direction. Also, a launchsystem 800 may be used to accelerate the member slide 80 on a descendingrail system 10 or ascending, as a roller coaster is pulled upwardlybefore its descent. The present invention 10 may have a series of gatesand sensors 810 placed at key locations throughout the zip line railsystem 10. The launch system 800 may displace or accelerate the memberslide 80 at any point or any location along the zip line rail system 10.

FIG. 4 also illustrates the use of the inline brake 600. The inlinebrake 600 may be configured opposite to that of the launch system 800.Both the inline brake 600 and the launch system 800 use the componentsdescribed herein. Further detail of said components can be seen in FIGS.5, 8, 9 and 10.

The zip line rail system 10 may use relay logic or a programmable logiccontroller to actuate or energize components having control of themember slide 80 location and speed.

FIG. 5 illustrates an embodiment of the member slide 80 having a frame150 and glide means 85 by which the member slide 80 may move withrespect to a rail or track 40. In one embodiment the glide means is awheel 90. There may be two wheels 90 on opposed sides of the memberslide frame 150. The wheels 90 may rotate about an axis of rotation 510.There may be two rails 40 separated by a distance 120. The space betweenthe two rails 40 may define a track member opening 370 by which aportion of the member slide frame 150 may extend through. The memberslide frame 150 may extend downwardly to a belt or strap 300. The beltor strap 300 may connect to a harness that the person may be wearing.

Each rail 40 may be supported by a plate 30, or by a series of plates asillustrated in FIGS. 1 and 8. The plate 30may have two plate arms 130that each rail 40 may rest upon. The plate 30 may have an upper supportportion 50 that may have a support member 20 extending there through.Also, there may be an inner channel 360 that the member slide 80 maymove through.

FIG. 5 also illustrates an in-line brake 600 that may be used with thepresent invention. The inline brake 600 may be comprised of a moveablecarriage 710 shown in detail in FIG. 10. Said moveable carriage 710 mayhave a contact member 630. The contact member 630 interferes with thepath of travel of the member slide 80. When the member slide 80 makescontact with the contact member 630 the member slide 80 may move inunison with the moveable carriage 710. Attaching a force creatingmechanism to the carriage 710 would control the movements of the memberslide 80. The carriage may be contained to a linear path parallel tothat of the zip line rail 10 by means of a track 680. Said track 680 maybe fastened to the zip line rail by a fixture 685. The fixture 685 mayconnect directly to the plate 30 or may be positioned with externalmeans such as an adjacent wall or structure.

FIG. 5 also shows the upper components of the member slide 80. The puck160 may be a wearing removable component which slides on the innersurface of the challenge course track 105. A sheath 260 protects thecritical load bearing members;

first member 220 and second member 230 seen in FIG. 6. First memberretention means 200 and second member retention means 210 securely holdthe puck 160 from passing upwardly on the slide member 160. The upperwasher 190 and lower washer 180 work together with the upper disk 170 toprovide support between the member retention means 200 and the puck 160.The entire upper assembly of the slide member 80 may be allowed to passthrough the inner channel 360.

FIG. 6 illustrates a sectional view of a modified non-single point offailure member slide 15. The member slide 15may have a first member 220that extends from a first member retention means 200 downwardly to afirst member lower retention means 470. The member slide 15 may have asecond member 230 that extends from a second member retention means 210downwardly to a second member lower retention means 480.

The member slide 15 may have an axle aperture 440 that an axle 430 maybe disposed there through. The wheels 90 may be rotatably disposed onthe axle 430.

In one embodiment the first member retention means 200 is disposedupwardly from an upper washer 190 and secures a first member 220 to thefirst member retention means 200. The first member 220 may extenddownwardly from the first member retention means 200 though an upperwasher 190, downwardly from the upper washer 190 through a lower washer180, downwardly from the lower washer 180 through an upper disk 170, anddownwardly from the upper disk 170 and through a lower disk 165, anddownwardly from the lower disk 165through the member slide frame 150 toa first member lower retention means 470.

In one embodiment the second member retention means 210 is disposedupwardly from an upper washer 190and secures a second member 230 to thesecond member retention means 210. The second member 230 may extenddownwardly from the second member retention means 210 though an upperwasher 190, downwardly from the upper washer 190 through a lower washer180, downwardly from the lower washer 180 through an upper disk 170, anddownwardly from the upper disk 170 and through a lower disk 165, anddownwardly from the lower disk 165 through the member slide frame 150 toa second member lower retention means 480.

FIG. 6 also shows the removable wearing components; the puck 160 and thesheath 260.

FIG. 7 illustrates an in-line brake system 600 that can be positionedanywhere along the zip line rail system 10, including the rail 40, zipline 110, zip track as disclosed in U.S. patent number PCT/US12/020,850,or the challenge course 100 and challenge course track 105. Any type ofdevice that slows down the speed of the member slide 80 may be used as abraking device. However the braking device of the present inventionallows the user to slow down or stop, and then continue traversing at aslow speed, such as walking with the member slide 80 being displacedalong the rail 40, or the challenge course track 105. In FIG. 7 thein-line brake 600 is shown at the bottom of an inclined rail 40.

FIG. 8 illustrates an embodiment of an inline brake 600 that may be usedwith the present invention 10. The inline brake 600 may have a contactmember 630 disposed so as to contact any portion of the member slide 80.After member slide 80 contacts the contact member 630 the contact member630 may cause a deceleration of the member slide 80 due to, for examplea force 640 directed the opposite way of the direction of travel 650 ofthe member slide 80. In one embodiment the force 640 may be a forcecreator 660, and the force creator may be a spring, a retraction devicesuch as those found at http://retract-a-strap.com/ on 19 Dec. 2013, oran eddy current brake used in roller coasters.

FIG. 8 illustrates the inline brake being in a braking position 620. Inthe braking position 620 the carriage 710 has not reached the end of thebraking track 680. Therefore, in the braking position 620 the contactmember 630 may be positioned perpendicular to the rails 40 and in thepath of travel of the member slide 80.

FIG. 9 illustrates the inline brake being in an open position 670. Afterthe member slide 80 is displaced past the contact member 630, then themember slide 80 can continue in its direction of travel 650. Afterwhich, a force creator 660, such as a spring or retraction strap maypull the inline brake carriage 710 back into a braking position 620, asillustrated in FIG. 8.

In one embodiment the inline brake 600 may be movably displaced along abraking track 680 and the braking track 680 may be disposed below therail 40, as seen in FIG. 5.

In one embodiment, when in the braking position 620, after the memberslide 80 contacts the inline brake 600, the inline brake 600 may have acarriage wheel 690 that may roll along the braking track 680 as theinline brake decelerates the member slide 80, as the member slide 80 andthe inline brake decelerate in unison while traveling along thedirection of travel 650. The carriage wheel 690 may then move to theside, which may cause the contact member 630 to be in an open position670. The carriage wheel 690 may be caused to move to the side byreaching, or example the end of the braking track 680, or a gap in thebraking track 680. The carriage wheel 690 may be attached to thecarriage 710 by means of a pivoting finger 730. The contact member 630may be securely fastened to the pivot finger 730. In this configurationthe contact member 630 may be moved out of the path of travel 650 whenthe pivot finger 730 is moved in relation to the carriage wheel 690.

FIG. 10 illustrates one embodiment of the carriage 710. FIG. 9 mayillustrate the carriage 710 in an upside down position. The carriage 710may have a carriage glide 720. In one embodiment the carriage glide 720may be a wheel, or a set of wheels that can be displaced along thebraking track 680 in both a direction of travel 650 and a direction offorce 640. The carriage 710 may have a pivot finger 730 pivotallyattached to the carriage 710 that the carriage wheel 690 may be rollablydisposed on. The contact member 630 may be fixed to the pivot finger 730so that it may be perpendicular to the brake track 680 when in thebraking position 620.

FIG. 11 illustrates an isometric view of the modified non-single pointof failure member slide 15. The member slide frame 150 may be made ofmore than one piece as to encapsulate the first member 220 and secondmember 230 once fully assembled.

The wheels 90 engagethe rails 40and may roll the length of the zip line rail 10. The rails40 may be fixed to the support plate 30. The support plate 30 may havean inner channel 360 through which the member slide 25 may be allowed topass. The length of the zip line rail 10 may be supported by the supportmember 20. The puck 160 may be a slider member for engagement with thechallenge course track 105. In this particular configuration the puck160 may be located below the rails 40.

FIG. 17 illustrates the embodiment of the offset non-single point offailure member slide 35. The offset member slide frame 145 may allow fortwo wheels 90 to be rollably fixed on axles 430. The wheels 90 may befixed to one side of the offset member slide frame 145 in a linearorientation. Said linear orientation may allow both wheels 90 to rollalong the length of one rail 40 as shown in FIG. 18. The offset memberslide 35 may also have similar components to that of the modifiednon-single point of failure member slide 15 shown in FIG. 11. The puck160may engage the challenge course track 105. The sheath may cover bothfirst member 220 and second member 230 in a similar configuration tothat shown in FIG. 6.

FIG. 18 illustrates the relation between the offset non-single point offailure member slide 35 and the zip line rail system 10. A plate orplates 30 are fixed to a support member 20. The plate may extenddownwardly to support a rail or rails 40. This configuration may allowfor one or both rails 40 to be of proper fit for wheels 90 to roll. Theoffset member slide 35 may only require one rolling surface or rail 40.This configuration may allow for a rail 40which only serves the purposeof retaining or capturing the offset member slide 35. FIG. 18 shows therail 40 opposite that of the wheels 90 serving the purpose of a captiverail 45. The offset member slide frame 145 may be curved in a way toorientate the belt or strap 300 underneath the wheels 90. Thisconfiguration may allow the wheels 90 to be properly guided along thelength of the rail 40. The captive rail 45 could be any structure thatspans the length of the rail 40 and does not require a proper rollablesurface.

The present invention 10 allows the member slide 80 to engage anddisengage from a launch system 800 without reversing, changing course,or otherwise altering the path of the member slide 80. The launch system800 may use the same components unique to the inline brake 600. It istherefore important to identify these unique components separately fromthe common technology such as winches and magnetic brakes which maychange the direction of operation depending on the configuration.

The present invention 10 allows the member slide 80 to engage the inlinebrake 600 while travelling the length of the rail 40, zip line 110, or achallenge course 100. The present invention 10 described allows theinline brake 600 to be of any length and placed at any location alongthe length of the rail 40, challenge course 100, or zip line 110.
